 ### URL 生成
 
 文件结构会自动生成简洁的 URL：
 
-- `docs/computer-science/index.mdx` → `/computer-science`
-- `docs/computer-science/data-structures/array/01-static-array.mdx` → `/computer-science/data-structures/array/static-array`
+- `docs/computer-science/index.md` → `/computer-science`
+- `docs/computer-science/data-structures/array/01-static-array.md` → `/computer-science/data-structures/array/static-array`
 
 ### 命名约定
 
 **文件夹:**
 
 - 使用 `kebab-case` 命名: `computer-science`, `data-structures`
-- 每个主题文件夹应该有一个 `index.mdx` 文件作为概述
+- 每个主题文件夹应该有一个 `index.md` 文件作为概述
 
 **文件:**
 
-- 使用 `kebab-case` 命名: `static-array.mdx`
+- 使用 `kebab-case` 命名: `static-array.md`
 - 使用数字前缀排序: `01-`, `02-`
 - 前缀会自动从最终 URL 中移除
